A custom configuration is useful for separating the scope of dependencies needed for a dedicated purpose.

Let's say you wanted to declare a dependency on the link:https://tomcat.apache.org/tomcat-9.0-doc/jasper-howto.html[Jasper Ant task] for the purpose of pre-compiling JSP files that should _not_ end up in the classpath for compiling your source code.
It's fairly simple to achieve that goal by introducing a custom configuration and using it in a task.
